Inspection of portable electrical equipment
Portable equipment is among the most common sources of faults in everyday operations. We inspect your devices flexibly and independently of the manufacturer to proactively eliminate the risk of personal injury and liability—without disrupting your workflows.

Legally compliant testing of portable equipment in accordance with DGUV V3
Portable electrical equipment is exposed to constant mechanical and thermal stress in demanding day-to-day operations, which often creates undetected safety risks. In accordance with the German Ordinance on Industrial Safety and Health (BetrSichV) and DGUV Regulation 3, the operator bears full responsibility for the safe condition of all work equipment—from IT infrastructure to heavy-duty power tools. Without a complete testing history maintained by qualified personnel, there is a risk of losing insurance coverage in the event of damage as well as the personal liability of management. Bittermann Elektrotechnik GmbH minimizes this risk through professional testing and guarantees you maximum legal certainty with minimal downtime.
Our testing services in detail
Our employees, qualified in accordance with the Ordinance on Industrial Safety and Health (according to TRBS 1203), carry out inspections strictly in line with the current standards DIN EN 50678 and DIN EN 50699. The structured process includes a precise visual inspection, detailed measurements of protective conductor and insulation resistance, as well as a final functional test. All generated data is recorded in an audit-proof database, so you receive legally defensible documentation for audits by employers' liability insurance associations and insurers. We also actively support you in preparing risk assessments in accordance with TRBS in order to define legally compliant and economically optimized testing intervals.
